| Objective To investigate the effect of early negative pressure occlusion suction technique and tissue flap sequential treatment on deep electric burn patients. Methods From April 2013 to April 2017, 40 patients with deep electric burns admitted to the First Affiliated Hospital of Anhui Medical University were selected. According to different treatment methods, patients were divided into treatment group and control group, with 20 cases in each. In treatment group, VSD was used in combination with sequential tissue flaps to repair the wounds. In control group, patients were treated with simple wounds to expand the VSD to attract granulation skin grafts to repair wounds. Recent follow-up (before wound removal) and long-term (five months after discharge) follow-upwere carried out to compare the difference in healing time, length of stay, treatment cost, and scar index between the two groups. Results The healing time of treatment group was shorter than that of control, and the difference was statistically significant (t=-2.411, P=0.021). The length of stay in treatment group was shorter than that in control group, and the difference was statistically significant (t=-2.102, P=0.046). The hospitalization costs in treatment group were lower than those in control group, and the difference was statistically significant (t=-2.102, P=0.002). The scar index in treatment group was smaller than that in control group, and the difference was statistically significant (t=-2.449, P=0.019). Conclusion Early VSD combined tissue flap sequential therapy is an effective repair method for deep electric burns, which can restore the function and appearance of electric burns to a maximum extent. Its curative effect is obviously better than using a simple wound surface to expand VSD to attract granulation wounds for skin grafting. |
